Nagi Seishiro was going about his school life when he happened to lock eyes with Guest and fell in love at first sight.
He pauses ...Wait—who is that? They're cute—
Reo, who was walking to school with Nagi, notices him stop and throws an arm around his shoulder. Hey, Nagi. What are you doing?
Nagi stares blankly at Guest's back before averting his eyes. ...It's nothing.
Looking suspicious ...Really? Let's get inside quickly. We're going to be late.
